2017 Toyota Tacoma Engine Problems

Truck has 116k miles, started losing power and acceleration diminished. CEL and Trac Off light came on. Pulled over twice after experiencing same issue. Took to mechanic and diagnostic code P0301 (cylinder 1 misfire). Replaced 6 spark plugs to be safe, and replaced broken coil in cylinder 1. Drove less than a mile and CEL came back on. Brought to dealership this time and they found a leak in the head gasket and noticed warping in cylinder 1, along with code P0301 still present. They reported back to me stating it needed a machinist to resurface the the cylinder head, that the repair is mechanical. Even outside of warranty this fix should not be costing $13,000. The truck has been properly maintained for the past 9 years, all oil services and replacing any wear and tear items. Mechanical (warping) is manufacturing issues.

I was driving on the highway when my vehicle suddenly lost power. The engine light and traction control light came on, and I lost power, and the engine started sputtering. I had to pull off to the side and put on hazards. My Tacoma would only drive about 25 MPH after this happened. Based on a quick search, this is a very common problem in 3rd-generation Tacomas!

2017 Toyota Tacoma double cab-V6 with 62K approx miles. On or around April 29th 2024, I was traveling in this truck when there was a sudden and complete loss of power, two check engine lights came on-The "trac off" light and the check engine light came on. I needed to pull over immediately for safety. I ended up driving the vehicle to the Toyota dealership in limp mode. The vehicle has sat at Tustin Toyota now for weeks with the Toyota dealership initially suggesting that a ACIS Flap broke off inside the intake manifold of the car. This was replaced and the vehicle is still providing the same alarms and still in limp mode. The initial fix(whihc did not fix the problem was a full replacement of the intake manifold). Now the dealer is suggesting that a piece(s) broke off the intake manifold and ended up inside the engine so now dealer is recommending and entire engine break down to attempt to further diagnose the situation. Again it looks to be a complete failuure of the ACIS system and the intake manifold. This problem has presented a EXTREME safety issue due to comp[lete loss for power initially then truck sits in LIMP Mode. Very dangerous!

Also the corrosive build up from the antifreeze will cause other parts and wires to not work, Attached is my part and the build up of antifreez before the leak,

NOTICING THAT AS I COME TO A STOP AT THE LAST SECOND THE DRIVETRAIN SEEMS TO SNAP OUT OF GEAR CAUSING A VERY LOUD CLUNK AT THIS POINT THE VEHICLE SEEMS TO FREE WHEEL FORWARD UNSAFELY. . THE JOLT YOU GET CAN BE COMPARED TO PUTTING THE VEHICLE INTO GEAR AT TOO HIGH OF AN IDOL, WHICH WILL CAUSE PREMATURE WEAR AND TEAR TO YOUR DRIVETRAIN. ALSO, THE ENGINE SEEMS TO SURGE AT IDOL WHILE IN GEAR AND IF YOU AREN'T READY FOR IT AND YOU ARE PARKING BEHIND SOMETHING, YOU RUN THE RISK OF HITTING IT.. I HAVE ADDRESSED THE DRIVETRAIN ISSUE WITH THE DEALER, BUT THEY SAY THEY CAN'T GET THIS TO HAPPEN FOR THEM. VERY INTERESTING CONSIDERING THERE SEEMS TO BE OTHERS WITH SIMILAR ISSUES.
